Title: Improvements in or relating to the bagging of agricultural crops and like commodities
IPC: B65B25/04
Filed: 1961-05-12
Abstract: 1,005,713. Weighing apparatus. J. C. DAVIES. Aug. 9, 1962 [May 12,1961], No. 17338/61. Heading G1W. In a bagging machine, for use with a weighing machine, a pivotable commodity containing feed shoot 6 Fig. 1 is held by a catch 11 in a discharge position until a predetermined load is in a bag (not shown) on the weigh platform 2 whereupon the catch is automatically released and the shoot pivots back to a rest position on a stop 9 by the action of a spring or by gravity. Material may be fed to the shoot from a hopper 10 or a conveyer. A spring loaded bolt 32 (Figs 1 + 3) on the shoot engages the catch 11 which is fixed to a spindle 12 rotatable in bearings 13 carried on a frame member 14 of the bagging machine. The spindle is fixed to a beam 15 which carries at one end a screwed rod 16 and at the other end a follower rod 21 with a roller 24. The rod 16 passes freely through a hole in a bracket 18 secured to the frame member 14, and a spring 19 on rod 16 urges the beam 15 in a clockwise direction. The follower roller 24 is thus urged against a weigher member 4 which is rigid with a weigh beam. As the weigh beam moves with the load on platform 2 so does the member 4 and hence the follower 21, 24 and beam 15. The catch 11 is thus disengaged from the shoot when a predetermined load is achieved which depends on the adjustment of spring 19 and the shoot pivots back to rest on the stop 9. The discharge may be thus stopped automatically before the required quantity of material is in the sack which is then topped up manually to the desired weight. As the shoot tips back a chain 25 pulls the beam 15 and follower unit upward away from the weigher which is a completely separate apparatus. There may be arrangements to stop the discharge from the hopper 10 to the shoot.

Abstract: 891,639. Grinding. SOC. DES LUNETIERS COTTET POICHET TAGNON & CIE. May 17, 1960 [June 2, 1959], No. 17411/60. Class 60. A machine for forming a surface, such as a spheroidal or toroidal surface, on a workpiece P, Fig. 2, comprises a mount B for the workpiece movable into successive positions by angular displacements about two axes x, x<SP>1</SP>, z ,  z<SP>1</SP>, at right angles to each other, the workpiece being engaged with a grinder M in each successive position. The mount for the workpiece is angularly-movable about the axis z, z<SP>1</SP>, in a gimbal D which, in turn, is angularly-movable about the axis x, x<SP>1</SP>, in a frame F. The angular positions of the mount relative to the gimbal and the gimbal relative to the frame may be determined either by pins V, W, engageable in holes in quadrants E, G, respectively, or by rotation of worms AA, BB, Fig. 3, engaging quadrant gears on the frame mount. The frame F may be movable along a slideway K by a screw J and handwheel I or pivotally mounted on a base to effect feed of the workpiece into the grinding wheel M having a plane or spherical surface, a comparitor L enabling the amount of feed to be determined. Alternatively, the feed may be effected by movement of the tool relative to the workpiece. Spherical surfaces are formed on the workpiece when the axes x, x<SP>1</SP>, and z ,  z<SP>1</SP>, are in the same plane and toroidal surfaces when the axes are in different planes. Electrical means under punched-card control may effect the successive movements of the worms AA, BB, the screw J being controlled by electro-mechanical or hydraulic devices also under punched-card control.

Abstract: 134,042. Bolton, M. A. Oct. 28, 1918. Spray carburettors; vaporizers, external.-In an engine which ignites its charges by the heat of compression, air, and fuel mixed with inert gases are compressed separately and delivered to the cylinder one after the other, the air entering during the early portion of the compression stroke and the fuel at the end of the compression and during the initial portion of the expansion stroke. In the construction shown in Fig. 2, a combustion cylinder 53 is charged with air by a pump 33 and with a mixture of fuel and moistened inert gases by a pump 43. Air is drawn into the pump 33 through passages 34, 37 and terminal ports 32 which are uncovered by the piston 17. Compressed air is discharged into the combustion cylinder through a valve-controlled passage 39 and a pipe 40. A valve casing 36 is located in an air supply passage 34 which surrounds heat-radiating fins 35. The pump 43 induces its charges through a passage 41 and terminal ports 42, and delivers into the combustion cylinder through a valve-controlled passage 44 communicating with pipe 48. The exhaust gases are discharged through a cooler, and then circulate through a jacket space 84 around the central cylinder before escaping to the atmosphere through a pipe 88 and a silencer 89. A bypass 91 on the pipe 88 conveys inert gases to a carburettor x having an outlet pipe 41 which opens into the admission ports 42 of the pump 43.

Filed: 1925-07-11
Abstract: 251,482. Langenburg, F. C., and Dickson, T. C. July 11, 1925. Physical or molecular structure, altering by mechanical treatment.-In a method of increasing the strength of guns and other hollow articles by expanding them beyond their elastic limit, the expansion is restricted positively to a predetermined amount. A gun-barrel A is subjected to internal hydraulic pressure and is enclosed in a casing B of slightly greater size to limit the expansion, allowance being made for the contraction of the finished article when the pressure is removed. A number of radial openings on three sides of the casing contain rods 20 which engage the gun A and actuate dials 21 to indicate when the operation has been completed. The ends of the gun are closed by plugs 11, 17, having packing rings 18 and secured by cross-heads 12, 13. The increase in the elastic limit may be varied by making the clearance between the gun and the casing differ along its length, and the casing is designed so that the breech end of the gun may move towards the muzzle end since the latter expands first and is gripped by the casing. In a modification an article F, Fig. 6, is stretched. longitudinally by internal pressure, the elongation being limited by the end G of the casing H. Circumferential clearance d may also be provided to allow lateral expansion. The expansion may be performed in stages with intermediate annealing, a different casing being employed for each stage. Specifications 251,480 and 251,481 are referred to.
